Waidangong 外丹功 has twelve movements plus one preliminary- movement and one Qi releasing movement. These movements are
divided into three sections: the first section includes the preliminary and the first four movements; the second, next four movements;
the third, the last four movements and the Qi-releasing movement. In learning Waidangong 外丹功, one must first do the preliminary
movement, then other movements, and finally, the Qi-releasing movement. This order must be strictly observed or there may be
undesirable effects. If one does not have enough time for doing all the movements, one can first do the preliminary movement, then
one or two other movements, and finally the Qi-releasing movement.
